Module tools 

call_tool’s handlers, one file per tool family (docs/specs/SPEC_LARGE_FILE_MODULE_ANALYSIS_2026_09_30.md §4.2 (a)). Each family’s call handles the tools it owns and returns not_in_family() for any other name, so no tool list is written twice.

Modules

open_prs 🔒

Open PRs in WhoIsWorkingOn (docs/specs/SPEC_AGENT_OVERLAP_AWARENESS_2026_10_10.md §3.5). They come from GitHub, so they cover agents on every computer. They are read through this agent’s own gh-agent (srv holds no GitHub credential), credited to the agent named by the <Agent>@<host>: title prefix CI requires, and cached for 2 minutes per repository. A PR without that prefix (a person’s or a bot’s, which the prefix rule exempts) is credited to its GitHub author, with no host.

overlap 🔒

Who else is working on the same thing (docs/specs/SPEC_AGENT_OVERLAP_AWARENESS_2026_10_10.md §3.2), and saying what you are working on (ClaimWork, ReleaseWork, §3.4).

panes 🔒

Panes, tabs and windows: open, name, arrange, focus, close; the agent’s own identity and lifecycle.

presets 🔒

Presets.

pty_shell 🔒

PtyShell*: interactive PTY shells.

shell 🔒

Shell, ShellStop, ShellInput, ShellStatus: pipe shells in the agent pane. ConnList: the connections those and PtyShell can run on.

ui 🔒

widgets 🔒
